The doomed Black Hawk chopper had been rehearsing Trump's evacuation route to a nuclear bunker before its deadly crash, online sleuths have claimed. American Airlines Flight 5342 was approaching Washington's Reagan National Airport at around 9pm on Wednesday when the military chopper and plane collided in mid-air, before falling into the Potomac River, killing 67 people. The deadly collision of a Black Hawk and passenger jet in Washington DC shocked the nation Wednesday, sparking an investigation into what caused the mid-air crash Pictured: Parts of the wreckage seen sitting in the Potomac River after Flight 5342 collided with an Army Black Hawk helicopter on Wednesday night, killing 67 people This has led a number of social media users to speculate that the chopper had been carrying out an evacuation and relocation training exercise which in a real-life situation would take a leader to a secure location such as a classified bunker. Emergency response teams are seen at the scene of the crash in the Potomac River A fireball then erupted in the night sky as the aircraft collided, before both the plane and helicopter tumbled into the icy Potomac River Authorities have not yet pinpointed a reason for the collision, but have said it could have been 'prevented', as many question how the two aircraft did not see each other on the clear night.
